It doesn't matter the scam status, as long as the coin is still in the GC user's watchlist or at the top of the search list, they will still list it. The service must pamper users so that they visit the site every day which is nothing but to maintain visitor traffic.
GC may already know that Game SQUID is part of a scam project because many victims have lost due to rug pulls, but GC only lists the trading volume of coins that have been listed on the exchange, so we know that many shitcoins can be easily listed on GC and CMC.
